Title: Improvements in or relating to pulse-to-shaft-position converter
IPC: G05D3/12
Filed: 1958-02-05
Abstract: 829,262. Clutches; controlling reversing gearing; stopping and starting machinery. OSHIMA, Y. Feb. 5, 1958 [March 31, 1957], No. 3708/58. Class 80 (2). [Also in Group XXXVIII] An electrically-operated clutch, Fig. 2, comprises a friction-plate 12 which is moved forward to engage a second plate 13 by three crystal bimorphs 14, each of which comprises, Fig. 3, two strips of crystal such as barium titanate arranged so as to flex, as shown by the dotted line, under the influence of an applied potential. In a device for converting a series of pulses into rotation of a shaft 2, Fig. 1, each pulse corresponding to the same increment of rotation, each pulse is applied to the left-hand input 6 of a flip-flop 10 to cause a crystal clutch A to couple a continuously-driven shaft 1 with the shaft 2 until, after the shaft 2 has moved through an increment of rotation, a pulse is produced by a commutator 4, fixed to the shaft 2, to reset the flip-flop 10, thereby disengaging the clutch A and engaging a braking clutch B. In a modification, Fig. 4, the shaft 2 can be driven in both directions. A pair of pulses applied simultaneously to input 6 of the flip-flop and to an input 17 of a gate G3 causes an incremental rotation in one direction while simultaneous pulses applied to the input 6 of the flipflop and to an input 18 of a gate G4 cause an increment of rotation in the other direction. A number of uses of the invention are mentioned including a rate-of-flow measuring device, Fig. 10B, in which pulses produced photo-electrically are passed to the device of Fig. 1, which the functions as a counter, during predetermined time periods.

Title: New metalliferous monoazo dyestuffs containing halogenotriazinylamino groups
Inventor: VELLINS CYRIL ERIC
IPC: C09B62/095
Filed: 1957-11-04
Abstract: The invention comprises water-soluble metalliferous monoazo dyes which, in the form of their free acids, are of formula: <FORM:0850559/IV (c)/1> wherein Y is an amino, methoxy or phenoxy group or an anilino group optionally containing one or two sulphonic acid groups. They may be prepared (1) by reacting an appropriate coppercontaining aminoazo dye with a dichloro -s-triazine containing a substituent Y; (2) by reacting a copper containing monoazo dye of the above formula but having a chlorine atom in place of the substituent Y, with a compound of formula H-Y and (3) by preparing the dyestuff of the above formula in its metal free form and treating it with a copper-yielding agent.  The dyes may be used to dye or print wool, silk, regenerated protein, polyamide or polyacrylonitrile fibres by conventional methods and are preferably used in conjunction with an alkaline agent to dye or print cellulosic textile materials in violet shades.  In examples: (1) the copper complex of the dyestuff 6-chloro -2- aminophenol -4- sulphonic acid --> 1-amino -8- naphthol -3 : 6-disulphonic acid is reacted with 2-phenoxy-or -methoxy -4 : 6- dichloro -striazine; (2) the dyestuff of (1) is treated successively with equimolar amounts of cyanuric chloride and metanilic acid aniline or ammonia.  The Provisional Specification describes copper- and nickelcontaining monoazo dyestuffs having linked thereto through a nitrogen atom a s-triazine group which is substituted by a halogen atom and by a substituent containing at most 13 carbon atoms.  The processes of preparation of the dyestuffs are similar to those specified above.  Many intermediate aminoazo dyestuffs and suitable components for their preparation, and components from which the substituents linked to the s-triazine ring are derived, are specified.  In examples the copper complex of the dye 2-amino-phenol -4- ethyl sulphone --> 1-amino-8- naphthol -3 : 6- disulphonic is reacted with 2-phenoxy -or-methoxy -4 : 6- dichloro -striazine, or with cyanuric chloride followed by metanilic acid, aniline or ammonia. Specification 797,946 also is referred to.

Title: Device for feeding two circuit systems with pressurised fluid
IPC: F04B49/10
Filed: 1975-01-29
Abstract: 1489438 Hydraulic control circuits POCLAIN 29 Jan 1975 [30 Jan 1974] 3951/75 Heading F1P In the circuit shown, Fig. 1 a prime-mover 1 drives four pumps 2-5 whose total possible output is greater than the available power of the primemover. Pumps 2, 3 supply a circuit 10 and the output of pump 3 is switchable between the circuit 10 and a reservoir 6 by a valve 7. Pumps 4, 5 may be switched between either circuit 10 or a circuit 11 by a manually operable valve 9. A further valve 8 switches the output of pump 4 between whichever circuit is being supplied by the pump 5 and the reservoir 6. The valves 7 and 8 are operated by actuators 38, 39 and 43, 44 which act against springs 40, 45. The cross-sectional areas of these actuators is related to the capacities of the pumps in such a way that the prime-mover is not overloaded and the maximum output is delivered where required. In prior art devices, the control of pump 3 took no account of the instantaneous value of P 1  1 , Fig. 2, and the control of pump 4 took no account of the instantaneous value of P 10 . Thus, to avoid overload, the output of pump 3 was returned to reservoir when P 10  reached PE, and similarly for pump 4 when P 11  reached PF. In the arrangement shown in Fig. 1, the output of pump 3 is only returned to reservoir if P 10  is in excess of the value represented by the point on the line JKM appropriate to the instantaneous value of P 11 , and similarly for pump 4.

Title: Improvements connected with automatic weighing apparatus incorporating weight recording means
Inventor: MOORHOUSE JOHN
IPC: G01G23/18
Filed: 1962-02-02
Abstract: 1,021,621. Weighing apparatus-photoelectric control. W. & T. AVERY Ltd. Feb. 1, 1963 [Feb. 2, 1962], No. 4010/62. Headings G1A and G1W. Automatic weighing apparatus incorporating weight recording means comprises a member coupled to a weight indicative part of the apparatus so as to be displaced if the apparatus is not in a state of static equilibrium, a photo-electric cell and light source whose interaction is controlled by alternate light interrupting and transmitting parts of the member, and switching means under control of a circuit containing the photo-electric cell, so as to prevent operation of the recording means until the apparatus is stationary. The weighing apparatus has a spindle carrying a weight encoded reticule. This reticule is furnished, adjacent its perimeter, with an arcuate series of light transmitting and interrupting areas, which are traversed between the photo-electric cell and the light source. Thus the photo-cell will produce signal pulses while the reticule is moving and a steady D.C. output when it is stationary. The photocell is connected in a circuit described in the Specification preventing operation of the recording e.g. printing mechanism unless the weighing apparatus is in equilibrium. Slight vibrations of the apparatus e.g. movements causing less than half the movement of the reticule from light to dark, will not prevent operation of the recording apparatus in the described circuit, and recording will be prevented in the event of failure of the light source.

A hand grenade for practice purposes comprises a clay body 1 having an axial bore lined by a sleeve 3 in which a cork wad 6 underlies an explosive charge 5 above which is a delay fuze 8 provided with a match head 9 and surrounded by a sleeve 7 ending in a paper collar 10 covering the charge 5. Colouring matter is incorporated in the clay. The sleeve 3 is of rolled paper and surrounded at its upper end by a rolled paper collar 4 and a waterproofing layer 2 applied to the body 1 is continued over the outer surface of the collar. A cap 14 covering the top of the grenade is integral with leaf springs 16 bent to engage a groove 18 in the body 1. The cap is bolted to a tubular element extending between the sleeves 3 and 7 and ending in tongues 12. A spring 15 surrounding the element 11 bears against the collar 4 and the cap 14. Before throwing the grenade, a cotter pin 21 is removed to' allow withdrawal of a safety pin 19. As soon as the springs 16 are released, the spring 15 forces the cap 14 off the body 1 and, as the tube 11 is withdrawn, the inner surfaces of the tongues 12 rub against the match head 9 and ignite it and the resultant flash ignites the fuze 8. In turn the fuze fires the explosive 5, which reduces the body 1 to a coloured dust by which hits are indicated.

Abstract: 814,969. Automatic voltage-control systems. TELEFUNKEN G.m.b.H. Feb. 14, 1956 [Feb. 16, 1955; April 28, 1955], No. 4533/56. Class 38 (4). [Also in Group XL (c)] In a circuit comprising a driver valve for generating a sawtooth current in an inductance and an E.H.T. voltage, a biasing voltage derived from voltage peaks occurring in the circuit during the flyback is applied to the control electrode of the tube in such a sense that if the voltage peaks decrease the average anode current is increased. In the booster-damper type sawtooth and E.H.T. voltage generator shown, flyback voltage peaks in winding 22 exceeding the H.T. voltage are rectified by a diode 21 and the resulting output voltage is used to maintain the average anode current such that the valve operates just above the knee of its anode voltage, anode current characteristic. The bias will also help to maintain the E.H.T. voltage constant. The tappings C1-C5 provide for adjustment of the sawtooth output current amplitude and the capacitor 25 maintains the flyback time constant as the tapping is changed. In an alternative circuit (Fig. 2, not shown) the rectifier 21 is connected to a tap on the transformer 3 through a capacitive potential divider and to earth, with a biasing source in series if desired. The driver valve 6 is preferably operated close to zero grid bias and its input wave is preferably derived for a circuit such as a cathode-coupled blocking oscillator, the operation of which is not affected by grid current in the driver valve.

Title: Improvements relating to the treatment of liver for the extraction of vitamin-containing oil therefrom
IPC: C11B1/00
Filed: 1945-02-23
Abstract: Vitamin-containing liver, particularly whale or fish liver is subdivided, dried (i.e., dehydrated, for example by heat) and then subjected to solvent extraction to separate the oil, a glyceride oil being added to the subdivided liver either before or during drying or both to prevent agglomeration of the liver particles being dried. Suitable glyceride oils are whale oil, a fish oil such as cod liver oil or a vegetable oil such as cottonseed oil, sesame oil or ground nut oil, while the solvent used for extraction may be trichlorethylene.  Oxidation of the oil extracted from the liver may be prevented by keeping the liver out of contact with the air, for example by the application of reduced pressure, right through the process from at least the commencement of the drying step to the end of the extraction step or to the end of the first stage of the extraction step in the case where the liver is subjected to more than one extraction. After being dried, the liver may be powdered before being passed on to the extractor.  Apparatus is described in which liver is minced, dried and pulverised in continuous manner and then passes to a batch-operated extraction apparatus comprising a cylindrical drum fitted with a stirrer.  The distillation apparatus for separating liver oil from solvent and the vacuum apparatus for keeping the liver out of contact with the air are also described.
